A PC-based system for virtual navigation of a wing-in-ground effect craft

摘要

The paper describes a PC-based system supporting virtual navigation of a wing-in-ground (WIG) effect craft, one of the fast sea transportation alternatives for the next millennium. ^The system incorporates several modules, some of which are still under development. ^The vehicle module dynamics features 6-DOF equations of motion with the effects of wind-wave perturbations and the action of the controls taken into account. ^The module of virtual navigation provides 3D representation of the vehicle, and other moving and still objects (conventional and fast ships, islands, buoys, beacons, etc.) in a realistic marine environment. ^The system incorporates effects of deterioration of visibility due to fog or darkness. ^When simulating navigation of large and very fast vehicles, it is imperative to model performance of radars in order to gain more time for decision making for collision avoidance. ^The system enables a user to both choose a WIG vehicle and create a navigational and sea environment prescribing courses and speeds of vehicles in traffic. ^(Author)
